Write a BASH shell script that uses a combination of the Linux commands cat, cut, grep, numaverage, numbound, uniq, sort, and wc to summarize the data contained in an external file Note 1: Students should use the man command to learn more about each of the above Linux commands. Note 2: Students should avoid using any Linux commands other than those listed above to complete their BASH script. The script should accept the name of the external file as a command-line argument The script should display the total number of particles recorded in the file The script should summarize the data of each unique particle (species): Note 1: Do NOT create temporary files to store data - chain commands together with piping. Note 2: All decimal values should be displayed to six (6) decimal places. Name of particle species Total number of occurrences of the species Minimum momentum of the species Maximum momentum of the species Average momentum of the species Two (2) data files are provided for use with the BASH script: small. dat and large. dat Use the small. dat file to test and perfect the BASH script Use the large. dat file to produce the output you will include in the Linux Lab submission

Code explained below

Explanation:

Please find the bash shell script to find the values of particle file

Sample input file:

NEUTRON 20.900103

PION- 0.215176

PION- 22.716532

NEUTRON 8.043279

PION+ 1.374297

PION- 0.313350

PION+ 0.167848

Program:

#! /bin/bash

if [ $# != 1 ]

then

  echo "Usage: $0 <input file>"

  exit

fi

#get the total lines in the file

numParticle=`wc -l $1|cut -d' ' -f1`

echo "Total Species: $numParticle"

echo

echo "Species Information:"

echo

#get the unique elements from file

uniqParticles=`cut -d" " -f1 $1|awk '{print$1}'|sort|uniq`

echo "Name Count Minimum Maximum Average"

echo " "

#loop the unique elements and do grep for each column values

for i in `echo $uniqParticles`

do

count=`grep -c $i $1`

#find the minimum element value

min=`grep $i $1|awk '{print $2}'|numbound -l`

#find the maximum element value

max=`grep $i $1|awk '{print $2}'|numbound`

#find the average of element value

avg=`grep $i $1|awk '{print $2}'|numaverage`

printf "%-10s %7s %14.6f %14.6f %14.6f\n" "$i" "$count" "$min" "$max" "$avg"

done

Output:

Total Species: 7

Species Information:

Name Count Minimum Maximum Average
